362 Mr. R. Trimen's descriptions of new 



distinctions are (2) three spots instead of two in costal 

 part of discal row ; and on under side (3) the nervures 

 not paler than the ground colour ; (4) the whitish cloud 

 on hind margin of fore wing ; and (5) the dull and ill- 

 developed state of the inner-marginal white stripe of the 

 hind wing, which in niveostriga is shining pure white. 



It gives me much pleasure to name this new butterfly 

 in honour of Pastor H. D. J. Wallengren, the dis- 

 tinguished Swedish lepidopterist, whose good fortune it 

 was to be the first to make known to Science a large 

 number of the South-African Rhopalocera. 



Like so many other novelties among the Hespericla, 

 this curious Thymelicus rewarded the unremitting re- 

 searches of Colonel Bowker, who discovered it in Zulu- 

 land in 1880. Later in the same year he sent an indi- 

 vidual taken at the Biggarsberg in Natal.

? . Pale reddish brown, with fuscous and transparent 

 spots. Fore wing : A central band of seven fuscous- 

 edged transparent spots, disposed thus, viz., an out- 

 wardly oblique row of three between costa and median 

 nervure (of which the 2nd and 3rd — larger than the 1st 

 — are in discoidal cell), and an inwardly oblique row of 

 four between 3rd median nervule and submedian nervure 

 (of which all are small but that between 2nd and 1st 

 median nervules, which is quadrate and much the 

 largest in the entire row of seven) ; near aj>ex a short 

 outwardly oblique costal row of four small transparent 

 spots, of which the first and last are minute ; between 

 the extremity of this subapical row and the 4th spot of 

 the median row, two fuscous spots, sometimes enlarged 

 and elongated longitudinally ; before middle, between 

 median and submedian nervures, a rather indistinct 

 fuscous spot. Hind wing : A transverse row of three 

 widely- separated fuscous spots before middle, one of 

 which (at extremity of discoidal cell) is more indistinct 

 than the others ; beyond middle a strongly-curved trans- 

 verse row of seven fuscous spots, of which the first next
